Recommendations wanted 4 exhaust system

Hey fellow Jeepers,
I have a beautiful 97 4.0 ZJ i bought 3-4 months ago, bought it for 2450$. It's got 211,119 miles on it.Inside was flawless, motor ran okay (had to replace the IAC, battery, and going to replace the exhaust manifold and exhaust system) which brings me to the question: What exhaust system can i get for the lowest price that'll make my jeep sound like a V8 (if possible)? I just love the sound of them when they pass, you cant miss it. There is a problem right now with my current system: The tailpipe is so close to the right rear tire that if the tailpipe moves, it'll bump against the tire. The Jeep came all the way from Tennessee, and my dad said it could be from when they moved it onto the truck to the dealer, causing the system to push to the motor?

Might also be that the rubber hanger bushing at the tailpipe is worn out. Check that out.

I don't know what to say as for the tailpipe but you can probably move it if you check the hangars.

As for a muffler replacement, I was running a Dynomax Super Turbo for a while; it was cheap and sounded nice but had a bit of drone. Didn't sound like a V8 but gave the Jeep more of an aggressive tone than stock.

Yesterday I upgraded to a Dynomax Ultra Flow SS. The muffler is straight through but actually has 0 drone inside, and sounds a lot better. Idle is pure V8 bliss, and driving is much more defined, but not too loud. I would compare the sound to a Flowmaster 70, but with a more aggressive sound when revved. I will not be changing setups again. You'll never get a V8 tone with an I6 but this is a great compromise.

@ZJTML:
i did take a look at the bushing, are they expensive?
@1996 ZJ, awesome, thats exactly what i want, the cool, aggressive sound.
Any idea of how much?

The muffler should be about 100-150$ depending on where you get it. I am in love with the sound compared to my old setup.

Best bet is to get on youtube and start typing different mufflers in on a 4.0l. Just make sure you are using headphones so you get the most realistic sound.

I wish I had a 5.2 the gas mileage is horrible on both of them so might as well have more power and nicer sound from the v8. If my 4.0 was stock I would sell it and get a 5.2 but its not so Im sticking with it for now.
